925 sterling silver. 925 represents the purity of silver. It's 92.5% silver mixed with 7.5% alloy. This is the low purity of silverware, just like the purity of 999 gold. Because pure silver is too soft and easily oxidizes. Silver is an active metal that easily reacts with sulfur in the air, causing silverware to turn black. Therefore, try to minimize contact with air when wearing it, and avoid wearing it in places with strong chemical gases. After touching sulfur soap, wipe dry. Due to the nature of silver itself, its texture is very soft and easily scratched. It is also not suitable for increasingly fine craftsmanship requirements and the ever-increasing rich and exaggerated designs of modern fashion accessories. In addition, since silver easily changes color and loses its luster, 7.5% alloy was added to give it the ideal hardness, brightness, and gloss, as well as antioxidant properties. Moreover, it can be inlaid with various gemstones, diamonds, jade, and bright stones. From then on, silver jewelry became fashionable with its bright color, unique style, exquisite craftsmanship, and affordable price range, becoming the new generation in the fashion industry. 925 sterling silver plated with platinum Silver is an unstable metal that can turn yellow and black due to external factors. Currently, there is no method in the world to prevent this change. 925 silver plated with white gold (palladium, rhodium) can effectively isolate 925 silver from external air contact. This white gold effect can generally last for 4-12 months depending on how well you protect your jewelry, after which it will revert back to the silver itself. 925 sterling silver (Thai silver color) In order to cover up the tendency of silver to tarnish easily, there is another method that involves directly sulfiding silver to prevent it from turning yellow or black. Sulfided silver presents an original and rustic effect, originating from Thailand and also known as "Thai Silver." Usually, this Thai silver silver is used for men's jewelry. 925 silver (plain silver) 92.5% silver + 7.5% copper alloy is the standard for pure silver, usually plated with platinum (rhodium) to prevent yellowing or blackening due to oxidation or sulfidation. Silver without platinum plating is called "plain silver."
